RadioShack’s chief financial officer resigned as the company reported a wider quarterly loss; Uroplasty’s financial chief, who had been on administrative leave since May, resigned; FreightCar America hired its new CFO from Federal Signal.

RadioShack’s same-store sales and gross margin fell markedly in the first quarter, as the retailer put CFO Dorvin Lively in charge of its growing but currently unprofitable store-within-a-store relationship with Target.

The results were poor enough to send RadioShack shares down about 10% to $5.38 apiece in recent trading, and they earlier touched their lowest level in more than 30 years, adjusted for stock splits, according to FactSet. They also prompted an analyst to ask the company whether its recently boosted dividend is safe and how it plans to deal with a debt maturity that’s still more than 15 months away.
